Newton’s Third Law of Motion For every action there is an equal but opposite reaction
Force Pair is the forces two objects apply to each other
Normal Force is the force that pushes perpendicular to the object’s surface
Elastic Collision when colliding objects bounce off each other
Noncontact Force is a force that one object can apply to another object without touching it

Weight is the gravitational force exerted on an object
Reference Point is the starting point you choose to describe the location, or position, of an object
Position is an object’s distance and direction from a reference point
Motion is the process of changing position
Displacement is the difference between the initial, or starting, position and the final position
Speed is a measure of the distance an object travels in a given amount of time
Velocity is the speed and direction of a moving object
Vector is a quantity that has both magnitude and direction
Acceleration is a measure of the change in velocity during a period of time
